A numerical study of viscoelastic buoyancy-driven unsteady natural convection boundary layer flow past a vertical cone embedded in a non-Darcian isotropic porous regime with transverse magnetic field applied normal to the surface is considered. The heat and mass flux at the surface of the cone is modeled as a power-law according to and respectively, where x denotes the coordinate along the slant face of the cone. Both Darcian drag and Forchheimer quadratic porous impedance are incorporated into the two-dimensional viscous flow model. The transient boundary layer equations are then non-dimensionalized and solved by the Crank-Nicolson implicit difference method. The velocity, temperature and concentration fields have been studied for the effect of Grashof number, Darcy number, Forchheimer number, Prandtl number, surface heat flux power-law exponent (m), surface mass flux power-law exponent (n), Schmidt number, buoyancy ratio parameter and semi-vertical angle of the cone. Present results for selected variables for the purely fluid regime are compared with the non-porous study by Hossain and Paul [9] and are found to be in excellent agreement. The local skin friction, Nusselt number and Sherwood number are also analyzed graphically. The study finds important applications in geophysical heat transfer, industrial manufacturing processes and hybrid solar energy systems.

chronic prostatitis/chronic pelvic pain syndrome is a prevalent urological disorder among men of all ages. Risk factors include conditions that facilitate introduction of bacteria into the urethra and prostate,Patients with chronic prostatitis/pelvic pain syndrome typically report genital or pelvic pain (in or around the penis, perineum, scrotum) lasting > 3 months. Treatment remains controversial and not consensual, the purpose of this article is to remind different therapeutic options available trough a literature review.

Migration is caused by a push from behind and/or a pull from an appealing prospect in front. The combination of push and pull factors and research into which specific determinants play a significant role in migration patterns has received a lot of attention in the empirical literature. Immigration is the main demographic factor and the government is supposed to have the ability to control its size and skill composition. In high income countries natural population growth nowadays is low (or negative) and overall population growth is mostly driven by immigration. A statistically significant role of migration in affecting the tax rate is found after controlling for income inequality and for several social and demographic variables that would be expected to reflect the government’s revenue needs and thus determine the tax rate. The aim of the present study is to examine if and how much the amount of public expenditures on social services has been affected by the migration among some Middle East countries over 1990-2007. JEL classification: H24, H75, J4.

The authors report a case of mycetoma of the foot (Madura foot). This is a patient of 34 yearswith a chronicswelling of the right foot withfistulasgiving a purulent yellow ishcontaining grains. Antibiotics and antifungaltreatments have not worked. Radical treatmentwasnecessary.

In this paper, the parameters governing the arm model of a robot has been studied through a numerical technique “fourth order non-linear extended RK method based on Centroidal Mean (RKCeM)”. The exact solutions of the system of second order equations representing the arm model of a Robot have been compared with the corresponding discrete solutions (approximate solutions) at different time and also the absolute error between the exact and discrete solutions has been determined.

As the present world challenges schools and the entire school community with many changes in the hope of improving the learning outcomes of students, schools and teachers, they are tasked with constantly upgrading the standards of education. Professional development has always been the focus of most of these improvements. In most schools and in the International Baccalaureate, teachers recognise that professional development does not end after the 1-hour or 3-days or 4-weeks sessions, it is continuous in nature and extends towards their everyday dealings. This study is a qualitative research that involves primary school teachers of an IB World School. The outcome of this research seems to capture the teachers’ perspective on professional development and how it has influenced their teaching practice. A review of relevant literature on the topic of professional development will give an idea on what professional development is, its purpose, how it has met the needs of teachers and how it has caused significant changes in teaching techniques. Mixed research methods were adopted in this study, the perspectives of a small group of primary teachers were recorded and analysed; allowing for comparisons with the results of the previous researches conducted in the field.

Leadership is perceived as being masculine and as a result women are less likely to be seen as leaders regardless of their capability. The purpose of this research is to identify the perception of the respondent about the domain of women as a leader in the field of technical and vocational based on the six domain of leadership and the level of six domain of leadership. A total of 18 female students from section 3 were chosen as respondents. A set of questionnaire was used as an instrument. It consists of two parts. Part A is about the demography of the respondent and part B is about the items to measure respondent’s perception of women as leaders in technical and vocational fields. The question in this study is based on the six domain of leadership. Data collected was processed using Statistics Package for Social Science (SPSS version 16.0) and were analyzed based on descriptive such as mean score, frequency and percentage. The outcome of this research shows that perception of respondent if women want to be or be a leader, they need have domain ethical in the leadership and the level of six domain show the high level result but only the domain inspirational have the moderate level.
